What does exhaust gas recirculation control circuit mean?

What does exhaust gas recirculation control circuit mean?

The exhaust gas recirculation (EGR) system helps minimize nitrogen oxide gases coming from your vehicle’s exhaust. The ECM/PCM detects an open circuit condition of an EGR motor control circuit for greater than 3 seconds.

How do I fix code P0404?

What repairs can fix the P0404 code?

1. Replacing the EGR valve if it stuck partly open from carbon buildup in the pintle area and cannot be cleaned.
2. Replacing the EGR position sensor if it is determined that it cannot give a correct input reading to the ECM when moved manually.

How do I fix error code P0403?

What repairs can fix the P0403 code?

1. Replacing the shorted or open EGR vacuum solenoid.
2. Replacing a corroded connector to the EGR vacuum control solenoid.
3. Repairing the wiring shorted to the EGR vacuum control solenoid.

What causes exhaust gas recirculation flow insufficient detected?

EGR valves can malfunction by becoming stuck open or closed due to carbon buildup. This is likely due to faulty or clogged EGR valve or carbon buildup in the intake manifold or on the EGR temperature sensor.

Can I drive with a P0406 code?

In vehicles with drivability concerns care should be taken when driving. The P0406 code should not prevent the vehicle from being driven to a safe location after the fault occurs.

What is a code P0402?

Diagnostic Trouble Code (DTC) P0402 stands for Exhaust Gas Recirculation “A” Flow Excessive Detected. It indicates that the powertrain control module (PCM) has detected excessive EGR. It is one of the generic diagnostic trouble codes in a number of makes and models that are related to the vehicle’s EGR.

What does exhaust gas recirculation cooler bypass control circuit open mean?

Exhaust Gas Recirculation Cooler Bypass Control Circuit /Open What does that mean? This is a generic powertrain diagnostic trouble code (DTC) and applies to many OBD-II vehicles (1996-newer). That may include but is not limited to vehicles from Ford, Dodge, Ram, Jeep, Chevrolet, Volkswagen, Mercedes, etc.

What is exhaust gas recirculation used for?

Exhaust gas recirculation Exhaust gas recirculation (EGR) is a method of modifying the inlet air to reduce NOx emissions at source, an approach widely and successfully used in automotive applications. Some of the exhaust gas is cooled and cleaned before recirculation to the scavenge air side.

What is exhaust gas recirculation (EGR)?

The exhaust gas recirculation (EGR) system helps minimize nitrogen oxide gases coming from your vehicle’s exhaust. This is important because nitrogen oxide gases are very harmful for the environment in significant amounts.

What does the p0403 code on an exhaust gas recirculation system mean?

The exhaust gas recirculation (EGR) system helps minimize nitrogen oxide gases coming from your vehicle’s exhaust. This is important because nitrogen oxide gases are very harmful for the environment in significant amounts. When your vehicle’s powertrain control module (PCM) detects a fault in your EGR system, the P0403 code could be set.
